5. Let's familiarize ourselves with the rotational Hamiltonian a bit more: 1 024(0) sin(0) O.. 24(0) 21E 250 4(0) 202 + yo) sin(0) 20 = 72 sin?(O) In the last problem set you analyzed the l = 1, m = 1 wavefunction. Let's do a harder one this time. a. If YO.4(0) = sin_(O) .ezid, what is m? Can you guess what l is equal to? Hint, the (2 pts) energy is E = 3 b. Now can you show...
